Genuine DoorKing 1601-111 carriage bolt, 5/16-18 x 2 in., stainless steel with white finish. Used in the drive shaft and bushing block assembly of the DoorKing 1601 barrier gate operator, where eight are required.
This bolt replaced the earlier 2615-673 (3/8-16 x 2-1/4) carriage bolt, which was used four per unit. Later 1601 units built after the Rev K housing change use the 1601-111 in the eight-bolt configuration.
Fits DoorKing 1601-380, 1601-381, 1601-480 and 1601-481 barrier gate operators. Sold each.
